Only 21 of 86 test_*.c group functions called their own nested
UNITY_BEGIN()/UNITY_END(). Each nested call reset Unity's global
NumberOfTests/TestFailures counters, so controller_test.c's final
`return UNITY_END();` -- the value meson test actually gates on --
only ever reflected whichever small window of tests ran since the
LAST nested reset, silently discarding pass/fail evidence for
everything before it (measured: 16 of 972 total tests in one run).
The same nested-BEGIN calls also caused PASS/FAIL banners to show
the wrong source file for tests in files that don't reset it
themselves (Unity.TestFile just carries over from whichever group
last called UNITY_BEGIN()).
Fix: replace every nested UNITY_BEGIN() with UnitySetTestFile(__FILE__)
(sets file attribution only, no counter reset) and drop the matching
UNITY_END(); add the same UnitySetTestFile(__FILE__) as the first
statement to the other group functions that had neither. The 2
genuinely standalone binaries (test_job_array_sched_push.c,
test_job_array_apiserver_push.c -- each has its own int main(), not
registered via controller_test.c's TEST() macro) are untouched.
Verified: single consolidated summary now reads
"972 Tests 0 Failures 0 Ignored OK", exactly matching the
ground-truth RUN_TEST call-site count across all 83 registered
group files (976 total minus 4 belonging to the 2 standalone
binaries). Every PASS/FAIL banner now names its own true source
file. Full xce-build.sh all regression pass clean (Ok: 9, Fail: 0).
No production code touched -- test-harness plumbing only.
restore_job_array()'s bulk-insert pass could fail partway through
(key_add() on realloc growth exhaustion), leaving an already-inserted
prefix permanently visible in c->jobmgr but excluded from
out_new_jobs -- so those elements existed and were individually
addressable but never reached HOOK_DETAIL_JOB_NEW, never scheduled or
pushed, not on this attempt or any later successful retry. A literal
violation of Requirements 2.3 and 9.4, tracked as bug-1443.
Adds kvmgr_reserve()/xzarray_reserve(), new purely-additive primitives
in shared kvmgr.c/zarray.c (following the existing kvmgr_capture_keys()
template -- bare extern function, no RTTI vtable slot, caller-holds-
write-lock contract), that pre-grow c->jobmgr's backing store before
the bulk-insert pass begins, closing the dominant N-scaling failure
trigger structurally.
Found a genuine off-by-one in the existing, unmodified
xzarray_ensure_items(): its strict less-than sufficiency check means
reserving exactly array_size and then performing array_size real
stores still triggers one more growth cycle on the last store.
Reserving array_size + 1 is the exact minimal correct compensation,
independently re-derived and confirmed by review with concrete
arithmetic.
For the now-much-narrower residual case (kvtab_add()'s own small
per-entry allocation, or a content collision -- both non-N-scaling,
honestly documented as still theoretically possible): restore_job_array()
now populates out_new_jobs with whatever prefix was genuinely inserted
before a failure, and apply_committed_entry() fires HOOK_DETAIL_JOB_NEW
for that non-empty partial prefix even when the overall return is
negative, while still propagating the negative rc so the LSN correctly
halts and the Live Apply Resource Fence still engages for the
remainder. A genuinely-inserted element is never left un-pushed again.
Task 7.1 of job-array-single-wal-record (Requirements 2.3, 9.4, 9.6).
Adds case WAL_JOB_ARRAY_SUBMIT to apply_committed_entry() (the live
apply pump / boot replay dispatch seam): calls restore_job_array()
(task 3.1) instead of restore_job(), and on success fires
HOOK_DETAIL_JOB_NEW exactly once carrying every newly created
element in restore_job_array()'s own out_new_jobs list -- never once
per element. No hook fires on an idempotent no-op (-EEXIST) or any
genuine construction failure, honestly propagating task 3.1's
documented bulk-insert-phase residual gap rather than papering over
it. apply_wal_entry() (standby catch-up) is untouched -- task 3.3.
Task 3.2 of job-array-single-wal-record.
Root cause (confirmed via targeted DIAG1419 logging on a live chaotic soak):
a client's commit-timeout retry during a genuine quorum-loss window appends
a second WAL_JOB_SUBMIT for the same jobid; the timed-out entry is never
retracted, so if it later achieves majority commit anyway both entries end
up committed. This is a legitimate, harmless duplicate — restore_job()'s own
-EEXIST correctly no-ops the second one — but replay_wal() tallied every raw
WAL_JOB_SUBMIT occurrence instead of genuine creations, so the duplicate
made new_job_submits disagree with jobmgr's real growth, firing a false
APPLY_DIVERGENT and deadlocking promotion.
Reverts the layer-3 claim/release machinery (job_wal_commit_claim/release,
claim_committed_job_submits, and their wiring): three attempts at preventing
the duplicate at submit/dispatch/commit time all failed to close the gap,
because the duplicate isn't a bug to prevent — a WAL entry can't be
retracted once appended, so any submit-time guard is structurally the wrong
layer.
Real fix: apply_committed_entry()'s WAL_JOB_SUBMIT case now returns 1 for a
genuine creation vs 0 for an idempotent no-op (restore_job() -EEXIST), and
replay_wal() only tallies new_job_submits_out on rc==1. Updates the affected
apply-seam/reapply-idempotency tests for the new return contract, and
reverses two apply-correctness tests whose premise (duplicate-jobid replay
must diverge) is now understood to be the actual bug rather than the
expected behavior — they now force divergence directly via the same
production fencing seam instead of relying on that trigger.
Verified: two consecutive 10-round chaotic soaks, zero divergence, zero job
loss, no election stall (previously reproduced within ~5 rounds).
Add apply_committed_entry(persist_t*, wal_type, lsn, payload, len) in
persist.c/persist.h as the single seam that turns a committed WAL
entry into an in-memory mutation plus its post-mutation notification
hook, covering job submit, job-state facts, queue control, and
worker control. Job-state facts route through 2.1's guard-only
apply_job_update_transition() core and fire a generic
HOOK_DETAIL_JOB_UPDATE, not per-type hooks — the wire format
(wal_jobstate_t {jobid, state}) cannot supply what the type-specific
cores/hooks require. This is a real, documented deviation from
design.md's per-type dispatch wording; tasks.md's Implementation
Notes flags it as unresolved and blocking for whoever wires this
into a live path (4.1/6.2/6.3).
Not yet wired into any live call site (replay wiring is 2.3).
